Abstract: The present disclosure provides a method and a device in a first node for wireless communication. The first node first performs a monitoring on first-type signalings, in which K1 first-type signalings are detected; and then transmits a first radio signal in a first time-frequency resource set; each of the K1 first-type signalings is associated to the first time-frequency resource set; a first signaling is a last first-type signaling of the K1 first-type signaling; the first radio signal is used for determining the receiving of first-type signaling(s) associated to the first time-frequency resource set before the first signaling; or is used for determining the decoding of bit blocks scheduled by the K1 first-type signalings. With the above-mentioned designs, the present disclosure manages to address missed detection of sidelink scheduling signaling caused when a data receiver sends NACK-only feedback in V2X, thereby further improving the entire system performance.

Abstract: The present disclosure provides a method and a device in a User Equipment (UE) and a base station used for wireless communications. The UE receives first information; determines first sub-information out of the M piece(s) of sub-information; receives a first radio signal in a first time-frequency resource set; the first information comprises the M piece(s) of sub-information, each of the M piece(s) of sub-information indicates a reference signal group, and a reference signal group comprises at least one reference signal. The first sub-information indicates a first reference signal group. A reference signal in a reference signal group indicated by at least one of the M piece(s) of sub-information is transmitted by a first serving cell, and the first serving cell is not added by the UE. The above method not only obtains performance advancement brought by serving cell handover, but also avoid time delay and service interrupt.

Abstract: The present disclosure provides a method and device used in wireless communication nodes. A first node receives a first radio signal; and transmits a first-type signaling on a first radio resource, the first-type signaling being used for indicating that the first radio signal is correctly received; or, transmits a second-type signaling on a second radio resource, the second-type signaling being used for indicating that the first radio signal is not correctly received; herein, time-domain resources occupied by the first radio resource and time-domain resource occupied by the second radio resources are orthogonal. Under Groupcast communication mode, the present disclosure transmits a retransmission signal to a UE that not correctly receives a radio signal through a UE that correctly receives a radio signal in the group, so as to achieve the purpose of improving signal received quality and resource utilization efficiency.

Abstract: The present disclosure provides a method and a device in a User Equipment (UE) and a base station for wireless communications. The UE receives a first signaling, and then transmits a first radio signal in a first subband. The first signaling comprises scheduling information of the first radio signal; the first signaling comprises a first field, the first field in the first signaling being used for determining a first reference-signal-resource group or the first subband, the first reference-signal-resource group comprising K1 first-type reference signal resource(s); whether the scheduling information of the first radio signal is non-codebook-based or codebook-based is related to the first field in the first signaling; the first subband is one of M subbands. The above method allows UE to flexibly switch between non-codebook-based and codebook-based uplink transmissions, thus avoiding the problem that a single uplink transmission mode cannot work on Unlicensed Spectrum.

Abstract: A method and a device in a UE and a base station for wireless communication are disclosed. The UE monitors a first sequence in a first time window. If the first sequence is detected in the first time window, performs a blind detection of a first signaling on K1 alternative RE set(s); the first signaling occupies one of K1 alternative RE set(s) in time-frequency domain, each RE included in K1 alternative RE set(s) belongs to an alternative time-frequency resource pool in a second time window in time domain. The first sequence is used for determining a start time of the alternative time-frequency resource pool in the second time window. The disclosure determines the start time of the alternative time-frequency resource pool by using the first sequence, increasing transmitting opportunities of control signalings without increasing number of times of blind detections, improving spectrum efficiency and overall system performance on unlicensed spectrum.
